Why does it matter what work was done to the car recently?

Because the bank 2 intake solenoid and its harness sit in a spot people only reach when they are doing something else. Intake manifold gaskets, rear bank spark plugs and coils, a starter, a knock sensor, a thermostat housing — all of them mean lifting and pulling this loom, and none of them include a check of it afterwards. So a connector left unlatched, a pin pushed out of its housing, or a wire stretched until it parts inside its insulation are all ordinary outcomes of unrelated work, and the code turns up somewhere between the drive home and a few weeks later. If there has been recent work, start at the connectors that job would have touched.

I checked continuity from end to end and the wire is broken. How do I find where?

Stop testing end to end and start testing in sections. The bank 2 branch is the longest run in this group and it usually passes through several intermediate connectors on its way across the engine. Split the circuit at each of those and test each segment separately. That narrows the search geometrically rather than leaving you unwrapping metres of loom, and in practice the fault often turns out to be at one of the junctions rather than in the wire between them — corrosion in a plug, or a terminal that has lost its grip.

There is an old taped-up repair in this harness. Is it worth redoing?

Yes, and be suspicious of it even if it currently tests fine. Repairs in this area tend to be made in place with a crimp connector and tape, because getting proper access is unpleasant. That kind of joint sits in a hot, damp, poorly ventilated part of the engine bay and corrodes inside the crimp where you cannot see it. A corroded joint can still pass a resistance check with almost no current flowing through it and then behave as an open once the module tries to drive the solenoid. If you find one on this circuit, cut it out and remake it as a sealed, heat-shrink-covered splice.

Can I keep driving with this?

Yes. The intake phaser parks at its default position and the engine runs on fixed valve timing on that bank. You will notice a slightly duller pull through the mid range if you are paying attention, and economy drops a little, but nothing here is unsafe and no damage accumulates. The reason to get to it is that one half of the engine is permanently giving up the torque and emissions benefit the other half still has, and the fix is often much cheaper than the code's reputation suggests — sometimes just a connector that was never latched.

P0083: Intake Valve Control Solenoid Circuit High (Bank 2)

An open circuit on the bank 2 intake valve control solenoid. The question that narrows this fastest is not electrical — it is what work has been done to this engine recently, because the far bank's harness is disturbed by jobs that have nothing to do with valve timing.

What does P0083 mean?

P0083 means the module found the bank 2 intake valve control solenoid circuit sitting high with no current flowing through it. The circuit is not complete.

The useful angle on this particular code is service history. Ask what has been done to the engine in the last few months before you pick up a meter.

The reason is structural. On most V engines the bank 2 intake solenoid and the harness branch that feeds it live underneath or behind the intake plenum, tucked against the far cylinder head. That area is not a place anyone visits to work on valve timing. It is a place people end up when they are doing something completely different: intake manifold gaskets, spark plugs and coils on the rear bank, a knock sensor, a starter, a coolant crossover, a valve cover gasket, a thermostat housing. Every one of those jobs involves lifting, unclipping, pulling or working around this loom, and none of them involves testing it afterwards.

That produces a recognisable pattern: a connector left unlatched, a pin backed out of its housing during removal, a loom stretched against a retaining clip until a conductor parts inside intact insulation, a plug reconnected at an angle so only some terminals engage. The code then shows up somewhere between the drive home and three weeks later. If the owner mentions any recent engine work, that is where to look first, and there is a decent chance the fix is free.

The second structural point concerns the length of the run. The bank 2 branch is the longest branch in this group. It leaves the main engine loom, crosses the engine, and typically passes through more clips, more bulkhead grommets and more intermediate connectors than the bank 1 branch does. Every connector in series is another place for continuity to be lost, and the failure rate of a circuit scales with how many junctions it contains rather than with how much wire it uses. So when you test, do not just check end to end and conclude the wire is broken somewhere. Break the circuit at each intermediate connector and test in sections. On a long branch that finds the fault in a fraction of the time and often finds it at a junction rather than in a wire.

Third, be sceptical of previous repairs. Because this branch is awkward to reach, past damage here is frequently repaired in place with a butt connector, a crimp and a wrap of tape rather than a proper sealed splice. Those repairs sit in a hot, damp, poorly ventilated part of the engine bay and corrode from the inside. A repair that reads fine with an ohmmeter can still fail under load, so if you find one, treat it as suspect and redo it properly with sealed connections.

With the intake phaser held at its rest position the engine drives close to normal, with a slightly duller mid range and a modest economy penalty. There is no mechanical urgency, but leaving an open circuit means one bank of the engine is permanently giving up the torque and emissions benefit the other bank still enjoys.

Common causes

Connector left unlatched or not fully seated after unrelated work on the rear or far cylinder head
Terminal pushed back out of the connector housing during a previous disassembly
Conductor broken inside intact insulation where the loom was stretched or levered against a clip
Corroded intermediate connector in the long harness branch serving bank 2
Previous in-place harness repair using an unsealed butt connector that has since corroded
Open winding inside the intake valve control solenoid
Broken or corroded pin at the module connector
Chafed-through conductor where the loom crosses the engine and has burned open
Loss of the ignition-switched supply feed shared with other solenoids

Symptoms

Check engine light on with P0083 stored
Fault appearing days or weeks after unrelated engine work was carried out
Duller mid-range response with intake phasing inactive on that bank
Small fuel economy penalty
Actual intake cam position for bank 2 frozen at its rest value on live data
Solenoid silent during a bidirectional actuation test
Bank 2 camshaft position correlation code appearing as a downstream consequence

Diagnostic steps

1.Ask what work has been done on this engine recently — intake gaskets, rear bank plugs and coils, starter, knock sensor, thermostat housing all involve disturbing this exact loom.
2.Inspect the bank 2 solenoid connector for a latch that is not engaged and for terminals pushed back out of the housing, which is often the whole fault and costs nothing to fix.
3.Trace the bank 2 harness branch and identify every intermediate connector between the module and the solenoid.
4.Test the circuit in sections at those intermediate connectors rather than end to end, since the long far-bank branch fails at junctions more often than in the middle of a wire.
5.Look specifically for previous in-place repairs — butt connectors, crimps, tape — and treat any you find as suspect regardless of what an ohmmeter says.
6.Confirm battery voltage is present at the solenoid's supply terminal with the ignition on before condemning the control side.
7.Measure the solenoid coil resistance across its terminals and compare with the bank 1 solenoid.
8.Flex the loom along its route while watching a live reading, since a conductor broken inside good insulation reconnects and separates with movement.
9.Redo any questionable repair with sealed, heat-shrink-protected connections rather than leaving an open crimp in a hot damp location.
10.Clear the code, run an actuation test to confirm the solenoid responds, then verify bank 2 cam position moves during a warm drive.

Repair cost

$0 – $850

The low end is genuinely zero when the fault turns out to be a connector left unlatched after other work, which is a real and common outcome on this code — worth checking before anything is booked. Diagnosis is $90 to $180. An intake valve control solenoid is $35 to $220 in parts, with labour from 0.3 hours on an accessible head up to 3 hours or more where bank 2 sits behind the intake plenum, giving $130 to $850 fitted. Repairing a break or redoing a corroded splice in the far-bank branch is $150 to $400, most of which is access. Testing the branch in sections rather than end to end is what keeps the diagnostic hours down on this one.

DIY vs shop

This is an intermediate DIY job. It usually involves diagnostic steps, specialty parts, and some careful work in tight spaces. If you have the tools and a service manual or trustworthy video for your specific vehicle, it is achievable in a weekend. Otherwise, a competent independent shop will be faster.
